Reaction Steps
Add a 1:2 ethanol:THF mixture to 20% palladium hydroxide on carbon (catalytic, 29.4 g) followed by 3-(4-benzyloxy-phenyl)-4-cyano-1-methyl-1H-pyrrole-2-carboxylic acid ethyl ester (97.93 g, 0.271 mol, prepared in examples E-6a or E-6b). Subject the reaction to 344.74 kPa (50 psi) of hydrogen gas. After 18 hours, filter and concentrate under reduced pressure. Purify the residue by flash chromatography eluting with ethyl acetate:hexanes to provide the title compound. Mass spectrum (m/e): 271.1 (M+1).
